Stenciling Technique Makes Nanostructures

Nadya Anscombe

As electronic devices get smaller and smaller, interconnecting them and addressing them electrically becomes a challenge. Single-molecule devices, for example, are of no use unless they can be integrated into complex integrated circuits and connected to nanoscale electrodes.
Conventional lithography can be used to make nanoelectrodes, but it is difficult to completely remove the resists that are used for optical or electron-beam lithography. This means that the surface of the electrode is not atomically clean, making it unsuitable for connecting a single-molecule device with a metallic...Read full article
